Hi guys;

Just installed OpenMediaVault 5 in the mmc of the ACEPC T11 Plus and all is working fine.
I only edited the grub file with the nomodeset option, to use as a headless server.

I have some errors, related to the bluetooth / wifi card and maybe intel audio. I don't use it, as my current build uses a gigabit LAN cable and I don't need audio at all...

This is the output:
root@openmediavault:~# dmesg --level=err

I know OpenMediavault runs on top of Debian 10 buster.

Maybe someone has some workaround to fix this errors? just to keep things clean and tidy.

Thanks in advance;

asch75,

Concerning the WiFi, take a look at the following post to see if it would help.

viewtopic.php?p=905#p905

I believe there is something unique about the WiFi that requires some sort of special driver or configuration script for the driver to start and/or run properly. ACEPC has their own "version" of Ubuntu 16.04 that includes this driver/configuration script, but I think that's the only one that will work without having to perform after installation tweaks, like mentioned in the post above.

For reference, it's not just with Linux. Those installing non ACEPC "versions" of Windows 10 can run into the same WiFi driver problem with certain Z8350 models. I did with my Wintel 8 Pro (T8) when I installed Windows 10 Pro 1909 from a Microsoft download rather than ACEPC's own. It took me a while to find the solution.

Hope this helps.

Edit: Just in case, the following is the download address to the Ubuntu 16.04 mentioned above...

Thanks Gabe. I saw the post viewtopic.php?p=905#p905 some time ago. It's part of my current fix, but is not enough. Also with the DMI issue, the brcmfmac43455-sdio.txt must be renamed to "brcmfmac43455-sdio.\$(DEFAULT_STRING)-\$(DEFAULT_STRING).txt"

This is my fix for missing files on debian 10 buster:
sudo su
cd /lib/firmware/brcm/
wget https://raw.githubusercontent.com/RPi-D ... 5-sdio.txt
ln -s brcmfmac43455-sdio.txt "brcmfmac43455-sdio.\$(DEFAULT_STRING)-\$(DEFAULT_STRING).txt"
wget https://github.com/RPi-Distro/bluez-fir ... 4345C0.hcd
wget https://github.com/RPi-Distro/firmware- ... o.clm_blob

But's not enough to fix all errors.
I will any other findings here.

asch75,

That was similar to the problem I was having when I did the clean install of Windows 10 Pro 1909. The solution I mentioned was the installation of a driver script that allowed the driver to start properly, or at least that's what I got out of what I read about it.

I didn't mention what I had found as I didn't find it here, or from ACEPC at all, but actually from a forum that was discussing the same type of issue with a Z8350 based model from a competitor. Once I installed that script in the system driver folder and ran the "Scan for hardware changes" in the device manager, the WiFi then started properly. I don't know if it also concerned the Bluetooth, as I had seen the WiFi problem first and was trying to fix that at the time.

Though I know they recommend that people do, I don't use the ACEPC version of Windows when I perform a clean install. I use the Microsoft versions of the ISO, then install the drivers from the driver file store I had saved from the unit prior to performing the clean install. I had done such with my Wintel 8 Pro, but it still needed that configuration script to run properly. I'm sure that, had I downloaded and used the official ACEPC drivers for that model, I wouldn't have needed it. When I get a new ACEPC, my process is setting up and updating the unit to current, then saving the driver file store, as well as a system image, then performing a clean install with the current version of Windows 10. I've done this with all three of my ACEPCs (Wintel 8 Pro, GK1 and AK3).

I plan on putting Ubuntu on my Wintel 8 Pro, as in comparison to my GK1 and AK3 it's just too slow for Windows 10 Pro. I know that it will be much more efficient with Ubuntu. The thing that scares me is the drivers, as I have only a beginner's level of experience with Linux, so I'm not very adept at knowing how to fix things, or even how to look to find out what needs to be fixed. "Fixed" as in drivers and such, that is.

If I run into a problem with the Ubuntu install I may hit you up for advice, if that's okay.

-------------------------------------------------------------------

For reference, in case anyone else sees this, the Windows based driver configuration script for the Z8350 based models that I'm referring to is titled "4345r6nvram.txt". With this said, because it's not an official ACEPC thing, it's a "use at your own risk" type of thing.

I just installed Debian Buster on my T11 Plus that I received yesterday. I was reading through this post (and linked posts) for help getting the wireless working but I was not getting any of the same results. I finally went back to the factory Windows install and found that my device does not have a Broadcom wireless card but actual a Realtek 8821cu card that shows as being connected via USB (does not show up in lspci but does show in lsusb)

I was able to get it working using the driver from here: https://github.com/brektrou/rtl8821CU

Here are my steps: Seems to work flawlessly after this. Posting in case anyone else finds a similar situation!

have you solved the problem ?

If you want to install the linux system by yourself, there is no help here. Due to the openness of the linux system, there is not enough experience to develop it. You need to install the driver by yourself to run normally.
